7. A flood control valve according to claim 1, wherein: sealing mechanism (7) include a closing plate (71), closing plate (71) fixed connection is between first sealing door (214) and second sealing door (215), just one is seted up on the upper surface of closing plate (71) and is hopper-shaped second collection hole (72) that sets up, the lower extreme of second collection hole (72) is run through and is seted up a second through-hole (73), a third through-hole (74) has been run through to have seted up on closing plate (71) corresponds the position of dead lever (32).

8. A flood control valve according to claim 5, wherein: four L-shaped placing grooves (54) are formed in the top end groove wall of the containing groove (26) corresponding to the four mounting blocks (51), and the four placing grooves (54) are respectively matched with the four mounting blocks (51).

9. A method of using a flood control valve according to any of claims 1 to 8, wherein: the method comprises the following steps:

the first step is as follows: when the water collecting device is closed, the water permeating into the containing groove (26) sequentially passes through the first collecting hole (312) and the first through hole (313) and falls into the connecting hole (23), the water permeating into the connecting hole (23) between the first sliding chute (24) and the first sealing plate (214) sequentially collects at the bottom of the connecting hole (23) through the second collecting hole (72) and the second through hole (73), when the water is more, the water generates floating force on the floating plate (33) and the floating air bag (34) and lifts the floating plate (33) and the floating air bag (34) upwards, the floating plate (33) lifts the lifting plate (35) upwards through the fixing rod (32), and when the lifting plate (35) is lifted to be abutted against the pressure sensor (38), the pressure sensor (38) is triggered, and the pressure sensor (38) transmits a signal to the controller (43), the controller (43) can transmit the signal to the outside through the antenna (45) to alarm the infiltration;

the second step is that: when the water draining device is opened, the driving motor (211) can be started, the driving motor (211) can drive the threaded rod (28) to go in, the threaded rod (28) drives the lifting plate (213) to ascend through matching with the threaded sleeve (212), and the lifting plate (213) can synchronously drive the first sealing door (214) and the second sealing door (215) to ascend, so that the water inlet (21), the water outlet (22) and the connecting hole (23) are opened, and water draining can be performed;

the third step: when the water is drained, water can upwards lift the floating plate (33) when flowing, the floating plate (33) can upwards lift, the lower end hole openings of the second through hole (73) and the third through hole (74) are sealed, the water can be prevented from upwards permeating, meanwhile, the lifting plate (213) can drive the mounting plate (37) to ascend into the lifting groove (41), the mounting plate (37) can prop against the touch switch (42), the controller (43) can be closed through the touch switch (42), and error signals can be outwards transmitted when the floating plate (33) lifts the touch pressure sensor (38);

the fourth step: when first sealing door (214) and second sealing door (215) rise, can remove the push down to two backup pads (64), a plurality of second springs (62) can make progress jacking bracing piece (63) this moment, and bracing piece (63) can make progress jacking bracing piece (64) and rise to with water inlet (21), the position that the lower extreme of delivery port (22) and connecting hole (23) flushed mutually, thereby make water can be directly outwards discharged along the plane under highly compressed condition, thereby avoid when first spout (24) and second spout (25) can influence the drainage, avoid its inside can get into debris and influence subsequent closing sealedly.
